RCW 62A.7-207
Goods must be kept separate; fungible goods.

(1) Unless the warehouse receipt otherwise provides, a warehouse operator must keep separate the goods covered by each receipt so as to permit at all times identification and delivery of those goods except that different lots of fungible goods may be commingled.

     (2) Fungible goods so commingled are owned in common by the persons entitled thereto and the warehouse operator is severally liable to each owner for that owner's share. Where because of over-issue a mass of fungible goods is insufficient to meet all the receipts which the warehouse operator has issued against it, the persons entitled include all holders to whom overissued receipts have been duly negotiated.
